About LPR’s: An “LPR” is a low pressure regulator that, when setup properly, will separate the solenoid’s air source from the valve’s air source while also lowering the solenoid’s operating pressure while simultaneously allowing the valve’s pressure to be raise. When properly setup and tuned, almost any lpr will give any impulse at least 200 more shots per fill. on the stock impulse, an lpr setup will give you 300-500 more shots per fill. Pretty much any lpr will greatly improve your impulses performance-the only lpr that really stands out from the crowd is the Akalmp SCM lpr. Any lpr will also make any impulse more consistant and it will enable it to shoot a lot faster with no shoot down.
About Valve Caps, VA’s, and LPR Nipples: Even more so than with the lprs, all these will give you exactly the same amount of performance. No one is better than the other as far as performance goes. All that you should consider when buying one is which can you get for the cheapest, and/or which one you think looks the best.
LPR Kits: There are three kinds of lpr kits for the impulse: Normal Cap/LPR/Nipple Kits, Cap/LPR Unit Kits, and One Unit Kits. There is also a VA kit. The Normal C/L/N kit is made by Smart Parts (see Smart Parts LPR). There are two C/L unit kits: the New Designz/ANS kit and the Function LPR kit (See ANS Jackhammer LPR and Function LPR). The only One Unit kit is made by Evil (see Evil Respirator). The only VA Kit is made by SPC (see CVS VA).
-You cannot use a VFF/HFV or a Tapeworm/GP Valve with any lpr setup.
-An lpr nipple is not a tapeworm.
-You CANNOT use an lpr on an impulse w/o an lpr nipple.
-Any lpr that you can use on a cocker that has 1/8 National Pipe Threads (meaning any cocker lpr except Hypbrid's and System-X's lpr's will work) will work as a lpr for an impulse.
-If you own an Adrenaline Impulse, contact Adrenaline (www.buypb.com
) for info about installing/buying a lpr/kit-installation for you and parts parts will be a bit different.
-To properly mount a lpr on a VA, you need to move the PRV to the rear of the impulse.
-An lpr does literally nothing for bolt stick aka FSDO.
-Make sure you are properly acquainted with how an impulse works, and specifically what different air modifications do.
Low Pressure Regulators:
PPS Rock LPR
–Very good lpr, the standard lpr by which all others are judged. Blow off valve built into the lpr that will blow if the pressure going into the lpr gets to high-uses when the lpr is used with an impulse because the PRV, or if you don’t have one, solenoid, would blow first. Externally adjustable by an allen key. Price- About $50.00
PPS Micro Rock LPR
–Same as normal rock, but without the blow off valve. About 2/3 of the size of the normal Rock. Externally adjustable by an allen key. Price- About $45.00
KAPP Rhino LPR
–Good lpr. Externally adjustable by a hand knob. Not tourney legal under any circumstances. Price- About $35.00
WORR Tickler LPR
–Very compact with consistancy it is hard to beat. Externally adjustable. Not tourney legal under any circumstances by a hand knob. Price- About $50.00
WORR Adjustible Sledgehammer LPR (aka Outkast LPR)
–A little bigger than a Tickler. Externally adjustable by an allen key. Tourney legal. Price- About $45.00
WORR Stock Sledgehammer LPR
–Very reliable for price, good all around lpr. Not externally adjustable. Adjusted with an allen key. Tourney legal. Price- About $30.00
Akalmp SCM LPR (I and II models)
–Best lpr in the world. It not only has just as high if not higher flow rates than any other lpr, but it is also the only pressure compensating lpr in the world. That means if your inline reg spikes, the SCM lpr is the only lpr that will adjust itself to keep its output from spiking too. Externally adjustable by an allen key. Tourney legal. Price- About $60.00
ANS Jack Hammer LPR
–Very very good impulse lpr. The lpr that all other lprs used with impulses are judged by. Very easy to clean, and high flow. Externally adjustible by a knob. Need to buy a locking jackhammer knob made by New Designz or modify it yourself to be tourney legal. Price- About $40.00 Also available in a kit from New Designz; The New Designz Ultimate Impulse LPR combo comes with a new designz lpr nipple, a new designz valve cap and a ANS Jackhammer II lpr. Price- About $90.00
Smart Parts LPR (aka Maxflo or Mini-Maxflo LPR)
–Almost exactly the same design as the Tickle. Very good performer and very small. Externally adjustable by a hand knob. Tourney legal. Needs to be regularly cleaned-one of the only lprs i can think of that does. Price- About $55.00 Also avalible in a kit from Smart Parts. Kit comes with Smart Parts lpr, smart parts valve cap, and smart parts lpr nipple.
Evil Resperator LPR
–A little tricky to install, this lpr is a unit that encompasses a lpr, a valve cap, and a lpr nipple all in one. Only can be used with an Evil valve, or a RIP valve. For optimum performance you need to heavily modify your impulse. Not suggested. Externally adjustable by an allen key. Tourney legal. Price- About $90.00
Evil Autococker Style LPR
–Pretty bad performer, not suggested. Externally adjustable by a hand knob with a hole for an allen key. Boarding on tourney illegal, but you could probably get away with it… if you even wanted to. Price- About $40.00
–Very small, and very poor performer. Worst lpr I have ever seen to date. Not suggested. Externally adjustable by a hand knob. Not tourney legal. Price- About $30.00
MacDev Sonic LPR
–Very small and very good performer. Externally adjustable by a hand knob. Not tourney legal. Price- About $50.00
Function LPR Valve Cap/LPR (one unit)
–Performs a little better than the Respirator. The Function LPR i tested had a scared valve cavity, which is probably just a minor machining flaw found just in the one is tested, but untill i can get my hands on another one, i can't say for sure. As far as how mine performed, this product isn’t worth buying if you can get another lpr out there, but i don't think it is a really bad performer. Comes with the valve cap and lpr as one unit and a normal lpr nipple on the side. Price- About $90.00
–Pretty bad performing lpr. Not suggested. Externally adjustable by an allen key. Tourney legal. Price- About $60.00
–Very very good flow, very compact, and very reliable. Externally adjustable by a hand knob. Not tourney legal. Price- About $60.00
Dye Rocket LPR
–While not suggested, it will work fine. Externally adjustable by a hand knob, and tourny legal. Price- About $60.00
Planet Eclipse DART LPR
–Very good performer. Not tourney legal. Externally adjustable by a hand knob. Price- About $60.00
Shocktech FGP LPR
–Very good performer. Big, just as big as a Rock. Externally adjustable by a hand knob. Not tourney legal stock, but can buy a new adjustable locking knob for it. Price- About $50.00
Belsales Evolution LPR
–Very good performer. Basically a sledgehammer w/ an externally adjustable cap on it. Not tourney legal. Price- About $60.00
Valve Caps and LPR Nipples:
New Designz High Volume Valve Cap LPR Kits (the different styles are all the same)

New Designz High Flow LPR Nipple
–Advertised as being a “high flow” nipple, but I notice no difference. Price- About $20.00
Function LPR Nipple

Vertical Adapters (aka Vertical ASA’s):
–Can be bought in a VFF setup, or in an LPR setup (can be upgraded with an lpr very easily later on from the VFF setup to the LPR setup). Requires a new hole to be drilled in the gun, and is not recommened for most. Extemely good performer though. Comes with a gauge for an lpr output and on for the gun’s input which is very handy. Price- W/O LPR $59.00 and W/ LPR $159.00
